Weather in Bengaluru in April
India · 20-year averages, April
A hard month. April asks something of you. Go in knowing what. Daytime highs average 35.1 °C and the afternoon is not negotiable — outdoor plans move to early morning or evening.
April ranks 11 of 12 — near the bottom of Bengaluru's year. December is the month that works, and the swing between the two is 47 points, which is a different holiday rather than a slightly better one.
Rain on 7 days, 2 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for heat management rather than style: shade, water, and a schedule that gives up on the middle of the day.
What the averages hide
Averages flatten a month, and this one hides a few things: 18 days clear 35 °C, so a serious heatwave is normal rather than notable. Across the twenty years measured, the hottest April day reached 39.9 °C and the coldest night fell to 16.3 °C, and the wettest single day dropped 75 mm — roughly 132% of the month's rain in one day.
This is the volatile part. April rainfall has ranged from 4 mm to 246 mm across the twenty years measured — a 242 mm spread around an average of 57 mm. The average is real but almost no individual April looks like it, so treat the figure as the middle of a wide range rather than a forecast.
Wind is light at 8.2 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 49%.
How April sits in the year
Temperatures hold steady either side: 34.7 °C in March, 35.1 here, 32.7 in May. Nothing about the timing within the month matters much. Rain is the thing that moves: May brings 7 days more of it, so the earlier half of a flexible trip is the safer half.
Daylight in April
Bengaluru sits close enough to the equator that daylight barely moves all year — 12.4 hours in April, against a range of just 1.5 hours across the whole calendar. Sunrise and sunset land at roughly the same time whenever you come.
An inland climate
Despite being inland, the year stays fairly even: 21.1 °C between the year's warmest afternoons and coldest nights. At 920 m the air is thin enough to matter — sun that burns faster than the temperature suggests, and nights that cool off quickly. Within April itself the daily swing is 14.1 °C, so mornings and afternoons need different clothes.
How busy it gets
Off season. The genuine off season: cheapest by a distance, with the caveat that some tours and restaurants close entirely.
Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.
April in Bengaluru versus nearby
If Bengaluru is one option among several, the nearby comparison is worth making. Mysuru is close enough to be a coin toss — within a degree on temperature, 2 days more rain. Kallakurichi is the weaker option in April — 4 °C warmer, 1 day less rain.
So: April is a compromise. December is 47 points better and is what Bengaluru is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
